React - optimal form (uncontrolled components) React - optimal way to create state. 871. To write an uncontrolled component, there is no need to write an event handler for every state update, and you can use a ref to access the value of the form from the DOM. First, developers have to choose between controlled and uncontrolled inputs. Now that we understand what React controlled and uncontrolled components are, lets review some key differences between them: Controlled components are predictable because the state of the form elements is handled by the component Uncontrolled Components: Uncontrolled Components are the components that are not controlled by the React state and are handled by the DOM (Document Object Model).

Now that we understand what React controlled and uncontrolled components are, lets review some key differences between them: Controlled components are predictable because the state of the form elements is handled by the component When comparing two React DOM elements of the same type, React looks at the attributes of both, keeps the same underlying DOM node, and only updates the changed What are React controlled components and uncontrolled components?
